Kathleen Carter
Fractional CMO & GTM Leader
Who Kathleen works with
Kathleen Carter is a Fractional CMO for UK-based and EMEA-facing B2B service firms, technical consultancies, specialist agencies, and tech-enabled service businesses typically generating £1M–£30M in revenue. Kathleen is GTM OS Certified, trained in GTM Partners' proven GTM expertise, frameworks, and systems. She works with mid-market companies navigating plateaued growth, post-founder-led sales transitions, or the integration of multiple brands and delivery hubs. Her client fit includes businesses offering complex, multi-service solutions across cloud services, data and AI, digital engineering, and creative or design services that sell into enterprise buying committees using vertical go-to-market strategies.
The GTM problems Kathleen solves
Kathleen addresses commercial growth challenges that emerge when B2B services rely on broad, un-segmented go-to-market strategies or founder-led sales motions. She resolves inconsistent pipeline generation, unclear positioning, and misalignments across marketing, sales, and proposition teams. Companies often engage Kathleen when existing data and tools lack coordinated execution, or when generalist marketing leadership and prior agency engagements fail to deliver operational outcomes. Operating across marketing, sales, and customer success, Kathleen applies the GTM Operating System (GTM OS) to link strategy, execution, and performance measurement into a unified commercial model.
Track record
Kathleen has delivered strategic positioning and go-to-market strategy for B2B service firms and agencies, including CreateFuture, Valtech, dentsu X, Wavemaker, Checkland Kindleysides, and Fiducial Communications. Through her work at AgentK, she helps businesses transition from broad market approaches into vertical demand generation models that produce qualified pipeline.
In Kathleen's words
London-based fractional CMO and GTM leader helping B2B service firms turn positioning into repeatable, qualified pipeline. I work with consultancies, specialist agencies, and tech-enabled service businesses that need clearer positioning, stronger demand generation, and tighter marketing-to-revenue alignment.
Why hire Kathleen instead of a traditional fractional CMO?
Kathleen is a GTM OS Certified fractional CMO & GTM leader, trained in GTM Partners’ proven GTM expertise, frameworks, and systems. Instead of filling one seat in one department, Kathleen works across marketing, sales and customer success, aligns your GTM across the organization, and guides the executive team from diagnosis to execution on the GTM Operating System™.
Capital is no longer cheap. You get senior GTM leadership and a proven operating system without the full-time executive price tag.
You hire the result, not the role.

- Frameworks, templates & tools — proven playbooks that guide you and your team toward the outcomes you’re after.
Partners pay a monthly or annual license to stay active. They're invested — and they stay sharp.
